Abstract
The Beryllium-7 (Be-7) concentrations in the atmosphere of Kuwait, as found by gamma-ray measurements for 243 air filters collected over a five-year p eriod, produced variable values ranging from 0.2 to 14.9 mBq/m(3) with a be havior pattern which has oscillatory characteristics, with increased activi ties occurring in the summer months of each year. The annual levels of occu rrence of 7Be were found to be correlate with the cyclic pattern resulting from the eleven-year temporal variations associated with the solar activity .
